gyrocam

[Saftari] was inspired by the technology used to capture video in the MotoGP World Championship races to create these instructables on how to build an auto-leveling Gyro camera. The setup he developed maintains the camera at a consistent level perpendicular to the earth no matter how much the motorcycle angles against the ground when turning.

The components involved include an Arduino Uno, a Triple Axis Accelerometer, a digital servo, and a Gyro breakout board. A bracket was built to house and secure the camera to the side of the vehicle. 2mm acrylic was used for this and was bent by heating up the material. Once complete, test runs were completed showcasing the capabilities of this type of Do-It-Yourself rig.

The quality of the video after the break is a little bit blurry, but it proves the point that a Gyro camera setup can be built at home:

[Derek] likes to get a little bit of drivers-eye footage when racing his motorcycle, but there’s an inherent problem with mounting a camera to a moving and tilting platform. When he leans into turns, the camera can’t keep the horizon level. Cinematography and electronics go well together. so [Derek] built a horizon-stabilized camera mount for motorcycle videography.

The build was inspired by footage shot from [Valentino Rossi’s bike in 2010. Of course the professional model costs a small fortune, but [Derek] managed to make his own out of 3D printed parts and a hobby servo.

Based on the Contour Roam camera, [Derek] had a pair of gears printed at Shapeways to fit over the camera and attach to a servo. The electronics are an ATMega32 with a L3G4200D gyroscope. When the ‘micro detects a change in the gyroscope it rotates the servo in the opposite direction, keeping the horizon in the video level.

It’s a very cool build, and judging from the action videos after the break, makes for awesome track footage.
